Method for El Nino/Southern Oscillation: ENSO by means of wavelet based data compression with appropriate support length of base function is proposed. Through the experiments with observed southern oscillation index, the proposed method is validated. Also a method for determination of appropriate support length is proposed and is validated.

The correlations between GBS, dengue, Multivariate El Nino Southern Oscillation Index (MEI) and local meteorological data were explored by the Spearman Rank correlations and cross-correlations between these time series. Poisson regression models were fitted to identify nonlinear associations between MEI and dengue. Cross wavelet analysis was applied to infer potential non-stationary oscillating...

a r t i c l e i n f o a b s t r a c t South Pacific subtropical density compensated temperature and salinity (spiciness) anomalies are known to be associated with decadal equatorial variability, however, the mechanisms by which such disturbances are generated, advect and the degree to which they modulate the equatorial thermocline remains controversial. During the late 1970's a climate regime t...

in this article the relationship between the amount of seasonal rainfall (autumn, winter and spring) and climate indices in iran have been studied. the climate indices (the southern oscillation(soi),the north atlantic oscillation(nao), arctic oscillation(ao),nino 3/4,the multivariate enso index(mei),trans_ nino index(tni) and the pacific decadal oscillation(pdo) are used as independent variable...

Si yo tuviera que señalar a los filósofos del Derecho me han proporcionado lo más importante bagaje intelectual hoy pueda tener, entre la media docena citaría (Kelsen, Hart, Ross, von Wright, Raz) ocuparían un lugar muy destacado Carlos Nino, de lado, y Alchourrón Eugenio Bulygin, otro. Tanto Nino como Bulygin enseñado mucho influido mucho, pero, además, fue gracias al primero tuve las primeras...

Middle reaches of the Yangtze River are the worst flooded segments along the Yangtze River. It is important to understand and study the variations of frequency and magnitude of historical floods in this area and how were they related to or affected by EI Niño in a long historical period. We applied the statistics and time series to study and analyze historical floods (1470–2000) and EI Niño eve...

دریاچه ارومیه از نظر منابع آب و محیط زیست یکی از مناطق مهم کشور به حساب می آید . با توجه به این که این دریاچه در معرض خشک شدن قرار دارد ، پیش بینی بارندگی و دبی در آن می تواند در برنامه ریزی موثر منابع آب و جلوگیری از خسارات دوره های خشکسالی نقش مهمی داشته باشد . به همین منظور در این تحقیق اثرات سیگنال های بزرگ مقیاس اقلیمی نظیر شاخص های soi ، nao و شاخص enso در مناطق nino4 ، nino3 t ، 2 + 1 ni...

This study presents the interannual variation in summer monsoon rainfall during El Nino Southern Oscillation (ENSO) phases, that is, and La Nina throughout Indian subcontinent its subregions 1986–2010. The analysis includes performance assessments of regional climate model (RegCM4) simulating through comparison with India Meteorological Department data. Observation clearly demonstrates Nino/La ...
